DOE experimental condensed matter physics principal investigator meeting

I am spending the next 2.5 days at the DOE's experimental CMP principal investigator meeting in the Washington DC area.  I'll try to blog a few highlights over the course of the meeting.  The basic idea is supposed to be to get all of the PIs together to talk about their latest stuff, and ideally to foster new collaborations and activities.  Judging from the people sitting around me, it looks like this will be an extremely strong meeting in terms of science.
